3. 240 VOLT SINGLE PHASE OPERATION
The motor supplied with your machine is a dual voltage,
120/240 volt motor. It is shipped ready-to-run for 120
volt operation. However, it can be converted for 240 volt
operation.
A qualified electrician should do the conversion, or the
machine can be taken to an Authorized Delta Service
Center. When completed, the machine must conform
to the National Electric Code and all local codes and
ordinances.
The machine is converted by re-wiring the motor for 240
volts, installing a 240 volt plug on the power supply cord
and replacing the switch (if necessary) with one that is
rated for 240 volt operation.
Be sure the 240 volt plug is only used in an outlet having
the same configuration as the plug illustrated in Fig. C.
No adapter should be used with the 240 volt plug.
EXTENSION CORDS
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-
wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the
machine's plug. When using an extension cord, be sure to use one heavy enough to carry the current of the
machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-
1 or D-2, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
